BACKGROUND OF THE INVENTION
In modern logistics development, how to improve the transportation efficiency and reduce the logistics costs has become an important issue. Multimodal transportation, as a high-efficiency mode of transportation, represents the development direction of the logistics industry. In China's Medium- and Long-Term Development Plan for Logistics Industry (2014-2020), it has been stressed 18 times to greatly develop multimodal transportation, and multimodal transportation is placed at the strategic level in development of the logistics industry. In addition, the 13th Five-Year Development Plan of China's Ministry of Transport has explicitly put forward a development goal of “seamless connection” of cargo transportation; under this Plan, multimodal transport equipment will be developed greatly, efforts should be made to build a multimodal transportation organization system in which facilities are connected efficiently, hubs transfer rapidly, information is interconnected and shared, equipment is standard and professional and services are integrally matched, and priority should be given to the development of a multimodal transportation system which takes goods loading devices and semitrailers as standard carrier units.

In order to solve the technical problem in the prior art that dock congestion and field shortage are caused because more vehicles, yards and workers need to be provided for increasing the efficiency of loading and unloading operations, the present application provides a straddle-type multimodal transportation interworking system, which is illustrated below.
As shown in FIG. 1, the straddle-type multimodal transportation interworking system at least comprises: a transportation system, a transfer apparatus 32, and a processor. The transportation system comprises a rail system 30 and a cargo vehicle 140.
The cargo vehicle 140 is movably provided on rail beams 170 of the rail system 30. The transfer apparatus 32 is used for transferring a goods loading device 33 from a transportation tool 35 to the cargo vehicle 140 and loading the same onto the cargo vehicle 140, or unloading the goods loading device 33 from the cargo vehicle 140 and conveying the same onto the transportation tool 35.
The processor is connected to the cargo vehicle 140 and the transfer apparatus 32 so as to control the transfer apparatus 32 to transfer the goods loading device 33, and after the goods loading device 33 is secured on the cargo vehicle 140, to control the cargo vehicle 140 to move on the rail beams;
When the goods loading device 33 needs to be transferred, the transfer apparatus 32 transfers the goods loading device 33 from a transportation tool 35 to the cargo vehicle 140 and loads the same onto the cargo vehicle 140, and the processor controls the cargo vehicle 140 to move on the rail beams, or the transfer apparatus 32 unloads the goods loading device 33 from the cargo vehicle 140 and conveys the same onto the transportation tool 35.
As shown in FIGS. 2 and 3, the transportation system further comprises an elevated pillar 160. There are two rail beams 170, which are provided on two opposite sides of the elevated pillar 160.
An upper surface of an upper portion of the elevated pillar 160 are bilaterally symmetrically provided with two rail grooves, which run through the elevated pillar 160 from the front end to the rear end of the elevated pillar 160. The two rail beams 170 are mounted in the two rail grooves. In the present embodiment, the elevated pillar 160 takes a “T” shape, and can be disposed in an isolation belt of a road conveniently and stably.
As shown in FIGS. 4 to 6, the cargo vehicle 140 comprises a base frame 141, at least two travelling wheels 142, at least two guide wheels 143, at least two stabilizing wheels 144, a travelling-driving device 145, and a train frame 146. The processor is connected to the travelling-driving device 145, controlling the travelling-driving device 145 to start or stop.
In order to increase the strength of the base frame 141, in the present embodiment, the base frame 141 adopts a welded-steel structure. The base frame 141 comprises two side frames 1411 and three cross beams 1412 arranged in parallel to one another. The three cross beams 1412 are arranged between the two side frames 1411. Each of the two side frames 1411 is provided with a fixed arm 1413. Specifically, the side frames 1411 and the cross beams 1412, as well as the side frames 1411 and the fixed arms 1413 are connected by welding in the present embodiment, or by riveting, screwing and the like in other embodiments.
The at least two travelling wheels 142 are rotatably disposed on the base frame 141 and rotatable on the rail beams. Specifically, the travelling wheels 142 are rotatable on an upper surface of travel rails of the rail beams to drive the cargo vehicle to move. In the present embodiment, there are two travelling wheels 142, which are disposed between two cross beams 1412 of the three cross beams 1412 respectively. In other embodiments, the number of the travelling wheels 142 may be three, four and the like, which may be set as required. The travelling wheel 142 has a structure consisting of an inner aluminium alloy hub for support and an outer rubber wheel outside the hub.
The at least two guide wheels 143 are rotatably disposed on the base frame 141, come into contact with two side surfaces connected to the upper surface of the travel rail of the rail beam, and can rotate on the side surfaces so as to guide and prevent the travelling wheel 142 from deflecting on the rail beam. In the present embodiment, for the sake of more stable guidance, there are four guide wheels 143, every two of which are in contact with one side surface. The four guide wheels 143 are disposed on four corners of the base frame 141 respectively. Each guide wheel 143 is of a solid rubber wheel structure with steel wheel protection.
The at least two stabilizing wheels 144 each are rotatably disposed at an end of the fixed arm 1413, come into contact with two side surfaces of the travel rail of the rail beam, and can rotate on the side surfaces so as to further prevent the travelling wheel 142 from deflecting on the rail beam and cause the travelling wheel 142 to travel more stably. The stabilizing wheel 144 adopts a solid rubber wheel structure with steel wheel protection.
The travelling-driving device 145 is fixed on the base frame 141 and connected to the at least two travelling wheels 142 for driving the at least two travelling wheels 142 to rotate. The at least two travelling wheels 142 can rotate on the upper surface of the travel rail of the rail beam to drive the cargo vehicle to move.
The travelling-driving device 145 comprises a gearbox (not shown) and an electric motor 1451. The electric motor 1451 is connected to the gearbox, and the gearbox is connected to the travelling wheel 142. The processor is connected to the electric motor 1452, so that when the electric motor 1452 is started, the processor controls the electric motor 1451 to drive the travelling wheel 142 to rotate on the travel rail of the rail beam. In the meanwhile, the at least two guide wheels 143 and the at least two stabilizing wheels 144 rotate on two side surfaces of the travel rail of the rail beam. The electric motor 1451 is powered by a way of third rail contact, and specifically the electric motor 1451 is a traction electric motor. In the present embodiment, the electric motor 1451 is connected to the gearbox by a coupling. The travelling wheel 142 is disposed on an output shaft of the gearbox.
The cargo vehicle 140 further comprises a traction beam 1471 and an elastic member 1472. The elastic member 1472 is fixed to the base frame. Specifically, the elastic member 1472 may be an air spring, a rubber spring, etc. The train frame 146 is disposed on the elastic member 1472 which elastically supports the train frame. In order to prevent the train frame 146 from moving in a traverse direction of the elastic member 1472, the traction beam 1471 may be provided. One end of the traction beam 1471 is fixed to the base frame 141 and specifically, the middle cross beam among the three cross beams 1412, and the other end thereof is fixed to the train frame 146. Moreover, the traction beam 1471 is obliquely connected between the base frame 141 and the train frame 146, i.e. a length of the traction beam 1471 is larger than a distance between the base frame 141 and the train frame 146.
The train frame 46 is disposed on the elastic member 1472. When the cargo vehicle 140 comprises the traction beam 1471, the other end of the traction beam 1471 is fixed to the train frame 146. The train frame 146 is used for carrying a goods loading device 110. In the present embodiment, the train frame 146 is provided as a flat plate shape. A first group of locks 1461, a second group of locks 1462 and two protruding beams 1463 are provided on a surface of the train frame 146 which is opposite to the suspension device 147, i.e. a surface for carrying the goods loading device 110. Specifically, the first group of locks 1461 consists of four embosses which are snap-fastened to the bottom of the goods loading device 110 so as to prevent displacement of the goods loading device 110 relative to the train frame 146 due to vibration and diversion during transportation. The second group of locks 1462 is located external to the first group of locks 1461.
The two protruding beams 1463 are provided at two ends of the train frame 146 respectively and located external to the first group of locks 1461. The second group of locks 1462 is provided on the two protruding beams 1463, so that a height of the second group of locks 1462 is higher than that of the first group of locks 1461. In other embodiments, the two protruding beams 1463 may not be provided, but multiple bumps may be provided, so that the height of the second lock group 1462 is higher than that of the first lock group 1461.
Thereby, when the goods loading device 110 with a small size such as 20 feet is placed on the train frame 146, a bottom of the 20-foot goods loading device 110 is snap-fastened to the first group of locks 1461. Since the second group of locks 1462 is external to the first group of locks 1461, even though the height of the second group of locks 1462 is higher than that of the first group of locks 1461, the second group of locks 1462 will not interfere with the 20-foot goods loading device 110, thereby having no impact on the transportation of the goods loading device 110.
If the goods loading device 110 with a larger size such as 40 feet or 45 feet is placed on the train frame 146, since the height of the second group of locks 1462 is higher than that of the first group of locks 1461, a bottom of the 40 or 45-foot goods loading device 110 can also be snap-fastened to the second group of locks 1462 without any effect from the first group of locks 1461. Therefore, while the goods loading device 110 is prevented from displacement relative to the train frame 46, an requirement of transporting different sizes of goods loading devices 110 can be satisfied.
Further, the cargo vehicle further comprises two safety wheels 148. The two safety wheels 148 are rotatably disposed on the base frame 141 and lie on two ends of the cargo vehicle in a moving direction thereof so as to serve as protection when the travelling wheels 142 are damaged. Specifically, the safety wheels 148 may be polyurethane rollers.
Further, anti-collision devices 149 are provided on the two ends of the cargo vehicle in the moving direction thereof so as to prevent shock on the cargo vehicle and guarantee the security of the cargo vehicle and transported cargoes in case of emergency. Specifically, in the present embodiment, the anti-collision devices 149 are disposed on two opposite ends of the train frame 146.
In the present application, the cargo vehicle transports the goods loading device 110 by the train frame 146 carrying the goods loading device 110 and by the travelling wheel 142 moving on the travel rail 172 to drive the cargo vehicle 140 to run on the rail beam 170. Therefore, no more vehicles are needed to transfer the goods loading device 110. Further, the technical problem in the prior art that dock congestion and field shortage are caused because more vehicles, yards and workers need to be provided for increasing the efficiency of loading and unloading operations is solved.
In addition, the cargo vehicle of the present application has a compact overall structure and a reasonable layout and furthermore, is secure and reliable.
An electric motor power supply system of the present application is powered by a third rail contact type conductive rail, and the straddle-type single-rail goods loading device transportation vehicles run in opposite directions on rails at two sides of the elevated pillar. Therefore, air space is utilized sufficiently without any effect on ground operations inside ports. The appearance of such vehicles can effectively solve existing problems in ports, and moreover, the vehicle has a simple structure and is secure and reliable.
The rail beam 170 comprises a seat 171 fixed to the elevated pillar 160 and a travel rail 172 fixed to the seat 171. In the present embodiment, the rail beam 170 is provided as an upside down T shape.
The at least two travelling wheels 142 are provided on an upper surface of the travel rail 172 and can rotate on the upper surface of the travel rail so as to drive the cargo vehicle to move. The at least two guide wheels 143 come into contact with two side surfaces connected with the upper surface of the travel rail of the rail beam respectively and can rotate on the side surfaces. The at least two stabilizing wheels 144 come into contact with the two side surfaces of the travel rail of the rail beam respectively and can rotate on the side surfaces.
Since a rail beam 170 is provided at each side of right and left sides of an upper surface of an upper portion of the elevated pillar 160 respectively, two-way transportation can be effected. In other embodiments, when two-way transportation is not required, only one rail beam 170 may be provided, at which point the rail beam 170 may be disposed in the middle of the upper portion of the elevated pillar 160.
In the present application, the transportation system transports the goods loading device 110 by the train frame 146 carrying the goods loading device 110 and by the travelling wheel 142 moving on the travel rail 172 to drive the cargo vehicle 140 to run on the rail beam 170. Therefore, no more vehicles are needed to transfer the goods loading device 110. Further, the technical problem in the prior art that dock congestion and field shortage are caused because more vehicles, yards and workers need to be provided for increasing the efficiency of loading and unloading operations is solved.

So far, the entire procedure that the goods loading device is transferred from the container truck or railway flatcar to the straddle-type multimodal transportation interworking system is completed. It is noteworthy that whether the telescopic mechanism 83 fails may be judged by the distance measuring element measuring an extension amount of the telescopic mechanism 83 and sending the measured extension amount to the controller. If the telescopic mechanism 83 fails, the warning device sends a failure warning.
A procedure for transferring the goods loading device from the straddle-type multimodal transportation interworking system to the container truck or railway flatcar is reverse to the procedure described above and thus is not detailed.
In a third type of structure, as shown in FIGS. 10 and 11, the transfer apparatus comprises: an underframe 99, a lift mechanism 92, a lifting table 910, a lift driving device 914, multiple travel wheels 93, a travel driving device 94, and a translation device 917. A processor is communicatively connected to the lift driving device 914 and the travel driving device 94.
The translation device 917 may be movably disposed on the underframe 99. Specifically, the translation device 917 comprises a translation plate 919 and a translation driving device 918. The translation plate 919 is located between the lift mechanism 92 and the underframe 99. One end of the translation driving device 918 is fixed to the translation plate 919, and the other end thereof is fixed to the underframe 99. The translation driving device 918 is used to drive the translation plate 919 to translate on the underframe 99. In the present embodiment, a movement direction of the translation plate 919 is different from that of the underframe 99. Specifically, the movement direction of the translation plate 919 is perpendicular to that of the underframe 99. The translation driving device 918 may be implemented as a hydraulic cylinder, an air cylinder, or a combination of an electric motor and rack and pinion. The processor is connected to the translation driving device.
The lift mechanism 92 is connected between the translation device 917 and the lifting table 910. By adjusting the lift mechanism 92, a distance between the translation device 917 and the lifting table 910 may be adjusted. In the present embodiment, the lift mechanism 92 is provided as an X-shape structure.
The lift driving device 914 is connected to the lift mechanism 92, and drives the lift mechanism 92 to raise or lower the lifting table 910 after the lift driving device 914 is started. The lift driving device comprises a lifting motor 95, a hydraulic station 96 connected to the lifting motor 95, a hydraulic cylinder 915 connecting the hydraulic station 96 to the lift mechanism 92.
The lifting table 910 is used to carry the goods loading device. In the present embodiment, the lifting table 910 is provided as a flat plate shape. A first group of locks 911, a second group of locks 912 and two protruding beams 913 are provided on a surface of the lifting table 910 which is opposite to the lift mechanism 92, i.e. a surface for carrying the goods loading device. Specifically, the first group of locks 911 consists of four embosses which are snap-fastened to the bottom of the goods loading device so as to prevent displacement of the goods loading device relative to the lifting table 910 due to vibration and diversion during transportation. The second group of locks 912 is external to the first group of locks 911.
The two protruding beams 913 are provided at two ends of the lifting table 910 respectively and located external to the first group of locks 911.

Thereby, when the goods loading device with a small size such as 20 feet is placed on the lifting table 910, a bottom of the 20-foot goods loading device is snap-fastened to the first group of locks 911. Since the second group of locks 912 is located external to the first group of locks 911, even though the height of the second group of locks 912 is higher than that of the first group of locks 911, the second group of locks 912 will not interfere with the 20-foot goods loading device, thereby causing no impact on the transportation of the goods loading device.
If the goods loading device with a larger size such as 40 feet or 45 feet is placed on the lifting table 910, since the height of the second group of locks 912 is higher than that of the first group of locks 911, a bottom of the 40 or 45-foot goods loading device can also be snap-fastened to the second group of locks 912 without any effect from the first group of locks 911. Therefore, while the goods loading device is prevented from displacement relative to the lifting table 910, an requirement of transporting different sizes of goods loading devices can be satisfied.
